Specification of Letters Patent.

Application filed January 3, 1917, Serial. No. 140,408. Renewed May 17, 1918. Serial No. 235,204.

To all whom t may concern:

Be it known that I, Haakon l?. HANLsoN, a citizen of the United States, residing at Albert Lea, in the county of Freeborn and State of Minnesota, have invented a new and useful Hay-Carrier, of which the following is a specification.

This invention has reference to hay car! riers, and its object is to provide a carrier readily adaptable to tracks of different widths without iinbalancing the carrier, and also to provide a lock structure for maintaining the fork pulley in an elevated position, and which will automatically lock and release. l

In accordance with the invention the carrier is provided with a dividedvframe with means for fastening the parts of the frame means arranged at different angles with parts so associated that variations in'width to conform the frame to variations in width of track are readily made. 'By having the fastening means associated at different angles the liability of loosening of the parts when adjusted to an extent to cause accidents is reduced to a negligible minimum.

The lock structure of the invention is of a nature in which a lock tripy or rope fas# teiiei is utilized to hold the fork in such ele* vated position as desired, and which is readily released when. the empty fork is returned along the track to the loading position.

The invention will be best understood from a consideration of the followingdetailed description, taken in connection with the accompanying drawings forming part of this specification with the further understanding that while the drawingsy show a practical form of the invention, the latter is not confined to any strict conformity wi th the showing of the drawings, but may be changed and Lmodified so long as `such changes and modifications come within the.

scope of the appended claims.

In the drawings l v Figure 1 is a vertical longitudinal section of the carrier mounted on the track.

Fig. 2 is an end elevation of thev carrier on the track with the llatter in cross-sectioii.

structure and coperating parts, showing alY each provided near the endswith wheels 5 suitably shaped to travel on the track 1. Y

The hay carrier is also provided with ar bodyV comprising two members 6 carried by a plate 7 and secured together by bolts y8 or by other means. Near one end the body member has va pulley 10 journaled therein, and near the other end the body member is provided with a swivel 11 and with an eye 12.

The plate 7 is formed atits central-por` tion with an opening 13 therethrough to acs commodate certain parts to be described, and the ends of the plate are formed withlugs 141 each with a passage therethrough.

Each truck 3 ands: oriopposite sides of its 'mid point is provided witlilate-rally eX- tended ears 15 and pendent ears 16, the latter beingV spaced apart to conform'vvith the spacing ofthe lugs 14 lengthwise of the plate 7 The truck vlilcmbersl are made fast to the plate 7 by bolts 17 traversing respective lugs 14 and ears 16. The truck members are also made fast to the plate 7 by bolts 18 traversing` the ears 15 and extended through laterally prolonged slotsl 19 in the plate 7 The width of the plate 7 is suflicient to permit adjustment of the truck members 3 and 4 toward each other between a minimum spacing represented by the width of the lugs 14 and a maximum spacing represented by the length of the slots 19, the bolts 17 being of sufficient `length te permit such adjustments. Since the bolts 17 are of a length to admit of the'treatest spacing of the trucks' 3 and 4, washers 20 are applied to the bolts exterior to the ears 16 when the trucks are in close adjustment, as shown in Fig. 2, or between the ears 1G and the respective lugs 14 when the trucks are more distantly placed. The washers 20 may be at all times present, and in the case of adjustments may be shifted from a position on the bolts 17 exterior to the ears 1G to another position between the ears 1G and the respective lugs 14.

The bolts 18 with the slots 19 in the plate 7 provide for lateral adjustment of the trucks 4, and while such mode of adjustment is effective so long as the bolts remain tight, it not infrequently happens in practice that such bolts so located will loosen not only to an extentI permitting rattling of the parts, but on occasions suflicient to permit the wheels 5 to run off the track, so that the hay carrier drops therefrom.

To avoid this trouble the lugs 14, ears 16l and bolts 17 are provided, these constituting an additional means for fastening the truck members 3 and 4 to the plate 7. The washers 20 always insure a tight fit of the parts when drawn up by the bolts 17, wherefore liability of any loosening of the truck members 3 and 4 with respect to the body of the hay carrier is reduced to a negligible minimum,

By arranging the bolts 17 and 18 at different angles with respect to each other, the truck members 3 and 4 and the plate 7 are secured together in two wholly independent ways, so that in the event of one set of fastening means loosening, the other set will surely hold the parts in firm engagement, thus insuring the desired operation of the device at all times and curing a defect which has been found to exist in hay carriers as heretofore constructed.

The hay carrier is provided with a fork wheel 21 mounted in a yoke 22 to which is attached a swivel 23 for the hay fork, the latter, however, not being shown. y

In the particular arrangement shown in the drawings the swivel 11 has one end of a chain 24 secured thereto, while the other end of the chain is secured to a rope fastener 25 in turn secured to one end of a rope 28 by means of which the hay carrier is actuated.

The rope fastener may be of the general character shown and described by application No. 115,007 filed by S. L. Hanson on August 15, 1916, or it may be of other similar character, and consists in general of a cage applicable tothe rope 2G and into which cage the untwisted strands of the rope may be inserted and knot-ted to prevent withdrawal. The fastener 25 forms an enlargement or head which is capable of utilization in connection with a locking structure to be described, the rope fastener operating as a trip in conjllnction with the locking structure.

Mounted upon a pivot pin 27 secured in and extending between the sides G of the body member is a locking dog 28 shown separately in Fig. 8. This dog is provided with two spaced jaws 29, 30, respectively, with the spacing suflicient to receive the trip member 25 between them. The jaw 29 is at one end of the dog and at the other end of the dog there is a nose 31 having approaching faces 32, 33, respectively. The face 32 is or may be in the form of an are struck from the center of the pivot 27, while the face 32 may be struck on another arc, although such particular formation is not necessary. The face 33 of the dog 28 has associated ears 34 for a purpose which will presently appear.

Extending between the side members G of the body of t-he hay carrier is another pivot pin 35 carrying a latch member 3G separately shown in Fig. 7. This latch member on one side of its pivot support is formed with two projecting fingers 37, 38, respectively, suitably spaced apart for a purpose which will presently appear. Gn the side of the pivot 35 remote from the fingers 37 38 the latch is formed with a nose 39 having faces 40 and 41 curved in general conformity with the curvature of the face's and of the dog 28, the curvature of the face 4l being substantially concentric with the pivot 35, while the curvature of the face 40 is such as to match the curvature of the face 32 when such faces are in engagement.

Extending through the latch or latch block 36 is a slot 42 traversed by a link 43 connected to the dog 28 by a pin 44 traversing the ears 34. The link 43 extends entirely through the latch block 3G and at the end of the link remote from that connected to the dog 28 it is threaded and has a nut applied thereto and is surrounded between the nut and the latch block by a spring 46, a washer 47 being interposed between the spring and the nut. The purpose of the spring 46 and link 43 is to hold the latch block and locking dog in contact with a constant tendency to move the latch block into locking relation to the locking dog.

Secured to the trackl is an adjustable stop 48 provided with lugs 49 in spaced relation and so situated as to be engaged by the Jfingers 37 or 38. The stop 48 is secured to the track by bolts 50 extending through aV clamp plate 51, which in conjunction with the bolts 50 clamp the stop to the track at any desired point.

Considering the rope fastener or trip 25 as properly located on the rope 26 and considering the dog 28 as having the trip 25 lodged between the jaws 29 and 30, and the locking dog `locked in the position just named by the .latch block 36'having its nose 39 in engagcmentwith the face 33 of the dog 28, all as indicated in Fig. 1, and further assuming that the hay carrier is moving toward the left as viewed in Fig. 1, which movement may be accomplished in any suitable manner, as by a rope attached to the eye 12, then one lug 49 of the stop 48 is in the path of the finger 38 of the latch block. As soon as the finger 38 engages the stop 48 with the hay carrier progressing toward the left as viewed in Fig. 1, the latch block 37 is rocked on its pivot 35 in a direction to move the nose 39 out of the path of the nose 31 of the block 28, the finger 37 moving between the lugs 49 of the stop 48. As soon as the latch block 28 is thus released the spring 46, put under additional tension by the rocking of the latch block 36 in the manner desired, causes the latch block 28 to rock on its pivot 27 in a direction to carry the jaw 30 out of the path of the trip 25, whereupon the weight of the fork wheel or pulley 21 and parts carried thereby pulls the rope 26, so that the fork drops and the trip 25 is carried away from the latch block 28, such block then being in the position indicated in Fig. 5. The hay carrier is, however, locked from movement along the track 1 by the engagement of the finger 31 between the lugs 49 of the stop v48, such position being indicated in Fig. 5. The latch block 36 cannot then rock on its pivot, because the locking dog 28 has so moved that its nose 31 is in the path of the nose 39 of the latch block, and neither can be moved by any force acting upon the hay carrier as a whole.

The fork may now be lowered to engage a load and by reversing the direction of the rope 26 the fork is raised until the trip 25 enters between the jaws 29 and 30 0f the dog 28, finally engaging the jaw 29. Further movement of the rope 26 causes a rocking of the dog 28 so that its nose 31 is moved out of the path of the nose 39 of the latch block, whereupon the pull on the rope 26 and the expansive force of the spring 46 causes the latch block to rock on its pivot 35 in adirection to carry the finger 37 from between the lugs 49 with the finger 38 raised, but on the side of the corresponding lug 49 towardk the direction in which the rope 26 tends to pull the hay carrier, so that the latter then moves along under the pull of theA rope 26. The rocking of the dog and latch block in the manner described, because of the action of the trip 25, causes a movement of the nose 39 into the path of the nose 31 and in en gagcment with the face 33 of the dog 28 so that the latter is effectively locked and the jaw 30 being in engagement with the pulley 10 prevents further rocking of the dog 28 to release the trip 25 from the holding effect of the jaw 29. A i

The rope lock and the action of the trip are entirely automatic, effective and certain. The fork wheel is locked and released entirely by the movement of the hay carrier, the locking and releasing taking place at any point which the operator may determine by adjustment of the stop 48 along the track 1.

lFurthermore, the hay carrier is readily adaptable to installed tracks of different widths, making it unnecessary for a purchaser to replace tracks already installed, and thus saving a purchaser the additional cost of track and its installation.

The lock structure is contained within the hay carrier and does not increase the width thereof, since the locking dog and latch member therefor extend in the direction of travel of the carrier.

l/hat is claimed is 1. A hayV carrier provided with opposed truck portions for engaging opposite sides of a track, and a body portion to which the truck portion is connected and with respect to which it is adjustable laterally of the direction of travel, and fastening means between the truck portion and the body por tion extending at different angles to provide independent fastening means each capable of holding the parts securely together in the event of loosening of the other fastenmg means.

2. A hay carrier comprising a body portion and a truck portion, with the latter composed of opposed members adjustable laterally of the direction of travel, fastening means between the body and truck portions extending in a plurality of directions, with each fastening means independent of the other fastening means, and said fastening means each providing for the lateral adjustment of the truck means with respect to the body member With the slots extending laterally of the direction of travel to permit separation and approach of the truck mem@ bers to accommodate the carrier to different Widths of track7 and other bolt connections between the truck members and the body member with the bolts extendingl laterally of the direction of travel and providing for the adj nstment of the truck members to different Widths of track independently of the bolt and slot connection.

4. A hay carrier having a body portion and truck members thereon, the body portion being provided with a plate having terminal lugs and lateral slots and each truck member having ears adapted to the lugs and other ears adapted to the slotted portions of the plate, a set of bolts traversing certain of the ears and the slots in the plate, and another set of bolts traversing` the other ears and the lugs of the plate, whereby the trucks may be adjusted laterally of the direction of travel to accommodate them to different Widths of track and each set of fastening means is independent in its action from the other set of fastening means.

In testimony, that I claim the foregoing as my own, I have hereto atlixed my signature in the presence of two Witnesses.
